WEBVTT ONE LONG-LASTING EFFECT IS THAT PARTICIPANTS WERE MORE FAMILIAR WITH THE DISEASE. JOE: QUIET NIGHT OUT THERE AS YOU LOOK LIVE OVER AFRICA -- EPHRATA. 48 DEGREES RIGHT NOW. WIND DYING OFF. WIND IS LETTING UP, CLEAR SKIES. CHILLY NIGHT BUT IT IS GOING TO GET COLDER. A FEW MORE CLOUDS MAY MOVE IN LATER TONIGHT AS ANOTHER FRONT MOVES IN. WE WILL PROBABLY DROP -- TOMORROW, A MIX OF SUN AND CLOUDS. 40'S TO MAYBE NEAR 50. CLOUDS WILL THICKEN TOMORROW. MORE SUNSHINE FARTHER SOUTH AND EAST. 52-56 DEGREES TOMORROW. PROBABLY NOT THAT WARM ON SUNDAY. A LOT OF SPOTS IN THE 40'S RIGHT NOW. 50'S IN READING AND CHAMBERSBURG. WE ARE NOT WORRIED ABOUT FREEZING TONIGHT. CLOUDS ARE HAVING A TOUGH TIME MAKING IT OVER THE MOUNTAINS. THIS IS A SECONDARY COLD FRONT COMING IN WITH MORE COLD AIR. THERE IS MORE COLD AIR IN CANADA. TWO COLD FRONTS HAVE COME THROUGH. ONE CAME THIS MORNING. THIS IS THE SECOND FRONT. THIS WILL REINFORCE THE AIR WE ARE GOING TO HAVE AN COLDER AIR WILL ARRIVE ON SUNDAY. THIS IS QUITE A CHANGE. CLEAR RIGHT NOW. SOME CLOUDS MAY SNEAK ACROSS THE MOUNTAINS LATER TONIGHT. I THINK WE WILL SEE A FEW BREAKS . IN THE AFTERNOON, IT WILL GET OVERCAST. THESE DOTS ON THE RADAR FROM COLD AIR COMING ACROSS THE GREAT LAKES. IT WILL BE A COLD MORNING ON SUNDAY. MORE CLOUDS AND PRECIPITATION WILL COME IN ON SUNDAY. THAT FREES WATCHES UP FOR ALL THE VALLEY. THAT IS FOR TOMORROW NIGHT AND SUNDAY NIGHT. I THINK SUNDAY IS THE BEST CHANCE WE HAVE OF GETTING TOWARD THE FREEZING POINT. LOOKS LIKE ON MONDAY THOUGH IT WILL BE A COOL DAY. TEMPERATURES TO TURN RIGHT BACK AROUND. WEDNESDAY OR THURSDAY, NEAR 70 DEGREES. PENN STATE TAKING ON THE BUCKEYES TOMORROW NIGHT. IT IS PRETTY COLD OUT THERE.
